It is useful in command-line and research-oriented image pipelines.
OGA at a glance
OGA
Convert to OGA when you want an explicitly audio-only Ogg-based file for open-format distribution, archival packaging, or technical workflows that use Vorbis, Opus, or FLAC inside Ogg.
It is useful for podcasts, spoken-word files, and music in open-source environments.
For the widest casual compatibility, MP3 or M4A remain safer defaults.
